this report reviews the various types of joints used in concrete pavements in great britain, and gives recommendations on their design, which is related to the method of pavement construction employed. the recommendations are based on the results obtained from a comprehensive programme of laboratory tests and site studies carried out jointly by the transport and road research laboratory and the cement and concrete association. standards for the rigidity of transverse joint assemblies are discussed, and a relaxation in the tolerances for alignment of dowel bars is suggested. the report also discusses simple procedures for site tests on joint assemblies before concreting to ensure satisfactory performance both during the construction and the subsequent life of the road.
